A search for pair production of the lightest chargino at root-s = 130.4 and 136.3 GeV has been carried out using the data sample corresponding to the 5.92 pb(-1) recorded by the DELPHI detector during the high energy run of LEP in the last period of 1995. The theoretical reference model has been the Minimal Supersymmetric Standard Model with R-parity conservation. The three topologies expected for the decay of a pair of charginos, namely two acoplanar leptons plus missing energy (ll), two jets and an isolated lepton plus missing (jjl) and missing energy in a hadronic environment (root-s), were investigated. No evidence of a signal was found. Lower mass limits were derived for various scenarios, including the case of a low mass difference between the chargino and the neutralino and of a light sneutrino. The mass limits range between 56.3 GeV/c(2) and the kinetic limit.

Abstract: A search for pair production of the lightest chargino at root-s = 130.4 and 136.3 GeV has been carried out using the data sample corresponding to the 5.92 pb(-1) recorded by the DELPHI detector during the high energy run of LEP in the last period of 1995. The theoretical reference model has been the Minimal Supersymmetric Standard Model with R-parity conservation. The three topologies expected for the decay of a pair of charginos, namely two acoplanar leptons plus missing energy (ll), two jets and an isolated lepton plus missing (jjl) and missing energy in a hadronic environment (root-s), were investigated. No evidence of a signal was found. Lower mass limits were derived for various scenarios, including the case of a low mass difference between the chargino and the neutralino and of a light sneutrino. The mass limits range between 56.3 GeV/c(2) and the kinetic limit.
